The purpose of this study was to analyze the morpho-functional features of the ovaries and uterus of sows with different genotypes for the estrogen receptor (ESR), prolactin receptor (PRLR), and follicle-stimulating hormone subunit beta (FSHβ) genes associated with reproductive traits. Healthy Large White sows were studied. The genotypic status of the ESR, PRLR, and FSHβ genes was detected by polymerase chain reaction-restriction fragment length polymorphism. The structure of the ovaries and uterus was studied using quantitative assessment of organs and histological research. Sows with the ESR BB genotype significantly exceeded animals with the ESR AA genotype in milk yield (by 0.3 kg) and in the number of piglets at birth (by 0.9 animals) and at weaning (by 0.7 animals). Sows with the ESR AB genotype were midway between those with ESR BB and ESR AA genotypes in terms of these reproductive traits. Animals with the PRLR AA genotype significantly exceeded those with the PRLR BB genotype in the number of piglets born (P < 0.05); the differences in litter weight at birth were not significant. Compared to other genotypes, sows with genotypes ESR BB (P < 0.05) and PRLR AA (AB) (P < 0.05) had larger uteruses and more yellow bodies, tertiary follicles, and primordial follicles in their ovaries. Animals with the FSHβ BB genotype significantly exceeded animals with the FSHβ AB genotype in the length of uterus by 21 cm (P < 0.05).

OBJECTIVE To assess the feasibility of a novel technique involving a vessel and tissue–sealing device (VTSD) for ovariectomy in chickens to evaluate the potential application of the procedure to other avian species. ANIMALS 20 domestic laying hens (Gallus domesticus), of which 10 were immature (< 4 months old) and 10 were adults (> 18 months old). PROCEDURES Ovariectomy was performed with a VTSD through a left lateral celiotomy. Birds were allowed to recover for 14 days after the procedure and then were euthanized for necropsy. A board-certified veterinary pathologist performed complete necropsies, with particular attention to identifying any remaining ovarian tissue. RESULTS All birds survived the procedure. For the mature and juvenile birds, the mean ± SD durations of anesthesia (interval from intubation to extubation) were 67.2 ± 7.6 minutes and 50.5 ± 5.1 minutes, respectively, and mean durations of surgery were 45.3 ± 8.5 minutes and 31.6 ± 5.1 minutes, respectively. Three birds had severe hemorrhage during ovariectomy. At necropsy, ovarian tissue was present grossly in 2 mature birds and histologically in 6 additional birds (2 mature and 4 juvenile birds), indicating incomplete excision in 8 (40%) birds. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that the evaluated VTSD can be used to successfully perform ovariectomies in both juvenile and mature chickens, although the procedure was associated with major hemorrhage and incomplete excision of ovarian tissue in some cases. Use of this VTSD for ovariectomy in birds of other species, particularly birds with reproductive tract disease, should be investigated.

OBJECTIVE To investigate the effect of an excessive tibial plateau angle (TPA) and change in compressive load on tensile forces experienced by the cranial cruciate, medial collateral, and lateral collateral ligaments (CCL, MCL, and LCL, respectively) of canine stifle joints. SAMPLE 16 cadaveric stifle joints from 16 orthopedically normal Beagles. PROCEDURES Stifle joints were categorized into unchanged (mean TPA, 30.4°) and excessive (mean TPA before and after modification, 31.2° and 41.1°, respectively) TPA groups. The excessive TPA group underwent a TPA-increasing procedure (curvilinear osteotomy of the proximal aspect of the tibia) to achieve the desired TPA. A robotic system was used to apply a 30- and 60-N compressive load to specimens. The craniomedial band of the CCL, caudolateral band of the CCL, MCL, and LCL were sequentially transected; load application was repeated after each transection. Orthogonal force components were measured in situ. Forces on ligaments were calculated after repeated output force measurements as the contribution of each component was eliminated. RESULTS Increasing the compressive load increased tensile forces on the craniomedial and caudolateral bands of the CCL, but not on the MCL or LCL, in specimens of both groups. At the 60-N load, tensile force on the craniomedial band, but not other ligaments, was greater for the excessive TPA group than for the unchanged TPA group. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that stress on the CCL may increase when the compressive load increases. The TPA-increasing procedure resulted in increased tensile force on the CCL at a 60-N compressive load without affecting forces on the MCL or LCL.

Aim of the present study was to determine the effect of the lactation number on milk production and to detect the most economical lactation period in Holstein dairy cows. Materials and The animal materials of the study were 392 Holstein dairy cows with a similar dry period and lactation length. The cows were divided into 6 groups according to the number of lactations. The groups were formed as 1st lactation (Group 1; n=67), 2nd lactation (Group 2; n=124), 3rd lactation (Group 3; n=51), 4th lactation (Group 4; n=62), 5th lactation (Group 5; n=41) and 6th lactation (Group 6; n=47).Average lactation milk yields for the 1st, 2nd, 3rd, 4th, 5th, and 6th lactations of the cows used in the study were 7860.03 kg, 9010.02 kg, 10207.15 kg, 10165.89 kg, 8430.57 kg and 8069.78 kg, respectively. It was determined that the highest milk production and highest daily income were obtained during the 3rd and 4th lactation periods (p<0.05).In conclusion, milk production increased in the first three lactations, 3 and 4 lactation remained stable and decreased in 5th and 6th lactations. But, regardless of the number of lactations during the first 6 lactation periods, it is considered economical to use healthy cows for milk production in dairy farms.

It was aimed to investigate the effects of ketamine combination administered with xylazine used for general anesthesia in dogs on arterial blood pressure, heart rate, and body temperature. Materials and Methods: In the study, a total of 20 dogs, 14 females and 6 males, from various breeds and ages 1 to 5, which undergone elective ovariohysterectomy or castration according to body weights. 1 mg/kg xylazine (xylazine hydrochloride, 23.3mg/ml, Xylazinbio 2% Bioveta®, Czechia) and 10 mg/kg ketamine (ketamine hydrochloride, 100 mg/ml, Ketasol 10% Richter® Pharma Ag, Austria) combination within a single injection with 21G needle were applied intramuscularly. The food and water access were ceased 12 hours before drug administration. Systolic and diastolic blood pressures, pulse measurements, and body temperatures were measured 3 times before and 5 times during anesthesia (at the 15th, 30th, 45th, 60th and 120th minutes of anesthesia) by using the AM6100 veterinary bedside monitor. Muff was placed to cover 1/3 of the proximal leg and for the artery to be recognizable by the microprocessor. Pulse rates were measured with electrodes connected to the device. Body temperature was measured by a rectal thermometer which was a part of the device. Measurements were taken before anesthesia was considered as control measurements.In systolic blood pressure, the recordings at 0, 15th, 30th mins have been found as statistically significant in relation to 45th, 60th, and 120th (p<0.05). In diastolic blood pressure, there were no significant differences recorded. The change between the preintervention and post-application has been found significant (p<0.001). Body temperature has shown a meaningful change in comparison to the starting point after the readings (p<0.001).Eventually, decreases in blood pressure, heartbeat, and body temperature were observed for the dogs that have been anesthetized with the combination of xylazine-ketamine.

Objective: Newborn calf diarrhea causes significant economic losses. Therefore, this study was aimed to determine the effect of adding probiotics on Total Antioxidant (TAS) and Total Oxidant (TOS) levels in routine treatment of calf diarrhea. Material-Method: The material of the study consisted of 12 calves, routine treatment (Group 1, n=6 calves) and probiotic group. (Group 2; n=6 calves).Results: TAS values increased statistically after treatment (P <0.05) in group 2 compared to pretreatment. Comparison of the groups after treatment revealed that TAS significantly increased (P <0.05) in group 2. While there was no statistical difference in TOS values between the groups a statistically significant increase (P <0.05) was detected after treatment compared to pretreatment.Conclusion: It was concluded that adding probiotics may be useful in addition to routine treatment in newborn calf diarrhea.

This study was designed to provide important clinical signs for tracking nerves in the mandible during regional anesthesia in Gurcu goats. Materials and methods: The study was conducted on the mandible bones of ten adult Gurcu goats of both sex (five male and five female). The mandible bone samples of naturally dead Gurcu goat were collected from Kafkas University veterinary faculty education, research, and application farm and processed as per the standard maceration technique. Altogether, 16 measurements were taken in the mandible bones of Gurcu goats by using a digital caliper and the results were expressed as mean and standard deviation.The obtained parameters from the present study can be useful for an extraoral and intraoral approach for nerve block of mental and mandibular nerve in the mandibular regions of Gurcu goat. According to results the mandibular length and height were 158.86±10.37 mm, 89.38±5.81 mm, in females and 198.93±3.85 mm, 114.5±7.29 mm, in males of Gurcu goats, respectively. The distance between the first inferior incisor tooth and mental foramen and to the first premolar tooth was 19.72±2.3, 19.26±0.44 mm in females, and 29.41±6.10, 21.83±1.02 mm, in males, respectively. The present study revealed that all the obtained parameters related to regional anesthesia showed a significant statistical difference (p<0.01**) between the males and females of Gurcu goat.It can be concluded from the present study that the various applied parameters of the present study are thought to assist clinicians in the administration of regional anesthesia in the lower jaw area (mandibular region) of the Gurcu goat.

The aim of this study is to determine the incidences of Malassezia infection and flea allergy in dogs with dermatitis complaints which were brought to veterinarians for examination in Ankara and Kırıkkale provinces. Materials and Methods: The material for this study consists of 40 pet dogs of different breeds genders and ages found in Ankara and Kırıkkale provinces of Turkey. Malassezia examination was conducted by staining smear samples taken with the acetate band method with Modified Wright’s Stain method. Flea existency examination was performed by using a flea comb.Out of the 40 dogs with dermatitis which were included in this study, 6 dogs (15%) were found to have Malassezia infection, 12 dogs (30%) were found to have flea infestation and 4 dogs (10%) were found to have together.In light of the results that were found in this study, Malassezia and flea infestation hold an important place for dogs which were brought with complaints of dermatitis to veterinary clinics for examination in Ankara and Kırıkkale provinces. Clinical veterinarians must keep in mind that, there is high incidence rates of these 2 dermatitis causing agents and also remember to especially consider them in the list of differential diagnosis.

The present study was carried out to investigate the possibility of using different levels of bee pollen and apigenin extract in beef meatballs to evaluate shelf-life, nutritional and quality properties of beef meatballs under different storage conditions. It was determined, using the HPLC method, that bee pollen contains a high level of apigenin under optimal conditions. Bee pollen and apigenin were added to meatballs at different concentrations in five groups. Meatballs were made with control, 1-2% bee pollens/apigenin. Quality and safety evaluation of meatballs were determined by sensory, physicochemical, biochemical and microbiological tests. The analyses were conducted at 1st, 3rd, 7th and 14th days of interval. A statistically significant decrease was found in FFA, POV and TBARS levels of meatballs on different days of storage (p<0.05). When compared to the control group, the bioactive compounds preserved the microbiological and chemical properties of meatballs during frozen storage (14 days).It was concluded that the extracts with 2% bee pollen concentrations can be used as biopreservative agents for meat and meat products.

It was aimed to investigate whether chia seeds provide an advantage during ultrasonographic imaging in cats when added to food by means of its high water-holding capacity. Ten healthy cats were ultrasonographically examined following 12- hour fasting period and after feeding with 3 different food types at 1-week intervals. Thus, 4 study group were formed as follows; FST; fasting 12- hour period, WF; feeding with wet cat food following 12- hour fasting period DWF; feeding with ½ of same wet food diluted with the same volume drinking water, CWF; feeding with ½ of same wet food mixed with 36 ml swollen chia seeds obtained by holding 2 hours 3ml chia seeds in 33 ml drinking water. Cats were evaluated ultrasonographically immediately after feeding, and at the 30th minutes and 60th minutes.Especially in terms of thickness, gastric wall evaluation was easier after food intake. In the CWF, the stomach was fully imaged on the frame at all times. The gastrointestinal tract content moved faster when cats were fed DWF or CWF; In the examination immediately after feeding the contents were in duodenum and seen in the jejunum and ileum in the 30- and 60-minutes’ examinations. CWF and DWF revealed more heterogeneous images then WF and also CWF provided better visualization for the intestinal canal wall layer.Ultrasonographic examination after feeding with chia seed added formula can be used as a complementary method following the fasting examination.
